It's been 3 days since anything was posted, so here's another attempt at a discussion-starter.
The Ms may be done with trades now, except for Edwin Encarnacion. Where he goes, and what the Ms can get for him will obviously have a bearing on what FA signings they make. But let's try to guess what signings might make a difference for 2019.
First Need -- an experienced Catcher
Here, the signing should be someone the staff can lean on. A.J. Ellis is, like Pat Borders, Jamie Burke, Josh Bard, and Chris Iannetta, a player whose best years have passed, but retains value in the experience and leadership he can bring. Of the FA catchers available, he looks to be the class of the field.
Next Need -- an experienced RH pitcher
The signing of Ervin Santana has in previous years seemed almost inevitable. Is this the year? His presence on the staff would bring balance and upside to the young rotation. While trading for Sonny Gray would be a better shot at upside for the following years, Ervin would be a stabilizing force for 2019, while Sheffield, Swanson and Dunn get polished at Tacoma and Arkansas.
Next Need -- a chance at another LH Ace
If there is any chance to sign Yusei Kikuchi, he would add to the LH-ness of the rotation, but his upside, paired with Marco Gonzales, makes the chances in 2020-2021 much brighter.
Overwhelming Need -- Dependable Bullpen Arms
Re-signing David Phelps would be a nice start here. Then, a LH reliever like Luis Avilan and/or Justin Wilson. Jake Diekman might also be a good bounce-back candidate. For another RH, Cody Allen might benefit from Safeco suppression of his HR tendencies.
Utility Needs -- A SS until J.P. Crawford is settled and ready
The Ms should really make signing Jose Iglesias a priority in my estimation. A superior glove, with an inconsistent bat, he's young enough to be an asset for several years, if required. Wilmer Flores is only 27, and also a decent UT candidate. A decent bat with a less expert glove, he can cover several positions, but probably not SS at an acceptable level. He would provide that by letting Dee Gordon move to SS, while he plays 2B. Either or both improve the Ms bench.
These are simply my take -- a few spuds in the pot might keep the site going for now, until Doc can provide some better new content.
